NCIt definition : A synthetic, colorless liquid that is very soluble in water. Styrene oxide is used
as a chemical intermediate in the production of styrene glycol and its derivatives,
cosmetics, surface coatings and other chemicals (agricultural and biological). It
is also used as a reactive diluent for epoxy resins and in cross-linked polyesters
and polyurethanes. Humans in the general population may be exposed to styrene oxide
by contact with contaminated air or water. It is reasonably anticipated to be a human
carcinogen. (NCI05);
